Particularly, the method comprises the steps of: receiving, through an upper layer, the reference signal configuration defined by P number of antenna ports; receiving, through M number of antenna ports, reference signals from the base station; grouping the P number of antenna ports into antenna port groups formed of the M number of antenna ports; calculating CQIs by using the reference signal corresponding to each of the antenna port groups on the basis of the assumption that predefined precoders are applied to the reference signals; and reporting, to the base station, N number of CQIs among the calculated CQIs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for reporting channel quality information in TDD type wireless communication system, and device therefor","description":"Disclosed is a method by which a terminal reports channel quality information (CQI) to a base station in a multi-antenna-based wireless communication system.
